DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Erika was
relocated near latitude 21.0 North, longitude 75.5 West. Erika is
moving toward the west-northwest near 20 mph (31 km/h), and this
general motion is expected to continue through tonight. A turn
toward the northwest and a decrease in forward speed are expected on
Sunday. On the forecast track Erika or its remnants will
continue to move near or over portions of eastern Cuba today
and move near central Cuba tonight.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Surface observations from Cuba and reports from an Air Force
Reserve Hurricane Hunter aircraft suggest that Erika is degenerating
to a trough of low pressure. If subsequent data confirm this,
advisories will be discontinued later this morning.
Tropical storm force winds extend outward up to 140 miles (220 km)
mainly over water to the east of the center.
The estimated minimum central pressure based on observations from
Cuba is 1010 mb (29.82 inches).
HAZARDS AFFECTING LAND
----------------------
RAINFALL: Erika is expected to produce total rainfall accumulations
of 3 to 6 inches with maximum amounts of 10 inches possible across
portions of the Dominican Republic, Haiti and eastern Cuba through
Sunday. These rains could cause life-threatening flash floods and
mud slides. In addition, the outer bands of Erika are also expected
to produce rainfall amounts of 1 to 3 inches across the Turks and
Caicos Islands as well as the southeastern and central Bahamas
through Sunday.
WIND: Tropical storm conditions across Haiti will gradually
subside this morning, and will continue in portions of the Turks
and Caicos Islands and the southeastern Bahamas for the next few
hours. Tropical storm conditions are possible over eastern Cuba
today.
